You don't have to use magnetism or electrical charge to store data. It can be done using light, or more rather, the reflection of it. Okay, if you want to be really specific, it's done using the interference of infrared and visible electromagnetic waves, but let's not worry too much about that!

Just as transistors revolutionized computers, by increasing the speed at which circuits could switch and perform math operations, the use of semiconductor devices in storage devices was aimed at producing the same outcome. Lets dissect SSDs.

It's magnetic. It's electric. It's photonic. No, this isn't going to be about a new superhero trio in the Marvel universe. This is all about our precious digital data. So let's prep for theatre, scrub our hands clean, and dig into the anatomy of what we use today to hold onto our trillions of digital bits.
